Mariners starting pitcher James Paxton left his start Thursday against the Angels with lower back stiffness, but manager Scott Servais told reporters afterward that the problem was "nothing serious" (via MLB.com).

"He's been checked out by doctors here," Servais said late Thursday. "Obviously that was his last outing before the All-Star break, so he'll have some time to calm it down and recoup and I fully expect him to come out of the break and be ready to go."
